Abstract: ABSTRACT OF THE DISCLOSURE         A method of lining a metallurgical assembly, in particular a coreless induction furnace comprises lining a furnace bottom, mounting a gauge for forming an inner wall of the lining on the lined bottom, and layer-by-layer filling a space provided between the gauge and an induction heater of the furnace with a lining mass while compacting each layer.  Thickness of each layer is 4 to 10 values of said space.  The layers are compacted by applying periodically repeated blows against the inner surface of the gauge and in the direction perpendicular to a plane tangential to this surface of the gauge.  The blows are applied with an interval being not less than the damping time of free oscillations o-f the furnace.  The inventive method makes it possible to ensure uniform compaction of the lining mass in the direction of crucible height and differentiated compaction in the direction of thickness thereof and thereby to increase the lining durability.

Abstract: ABSTRACT OF THE DISCLOSURE         A posterior chamber lens including a plano-convex poly-methylmethacrylate (PMMA) optic and two smooth, monofilament, curved, flexible loops attached to and extending from the optic. Each of the loops, also of PMMA, is angulated 10° anteriorly from the plano surface of the optic.  The optic is reversed such that the convex surface is posterior and is provided with positioning holes.  The PMMA decreasing radius loops and optic provide for a flexible, lightweight and edge-thin lens and loops.  The PMMA loops' angulation and plano-convex optic design vault the lens away from the iris.  The positioning holes are situated at 12 and 6 o'clock positions and are of a predetermined desired size.  A second embodiment of the PMMA lens includes PMMA loops which are substant-ially parallel to the planar surface of the lens.  A third embodi-ment of the PMMA lens includes PMMA loops which are 10° anteriorly from the convex surface of the optic   A fourth embodiment of the PMMA lens includes closed PMMA loops which can be angulated from the surface of the lens.  A small loop can be provided at the end of each open loop of decreasing radius.  The loop can reverse or fold back and secure to the optic.  A geometrical member can be positioned at an end of each loop.  One loop can be open and another loop can be closed.  The loop can be dialed into position by the junction between one of the loops and the optic.  The loops attached to the optic can be identical with respect to each other or assume different geometrical shapes with respect to each other.

Abstract: Abstract A rolling thrust bearing for use in a scroll type positive fluid displacement apparatus is disclosed.  In the invention, a plurality of ball bearings spaced apart in cavities formed in a bearing cage are operative to transmit an axial force between a supporting frame and an orbiting scroll member.  The bearing cage rotates within a groove in which it is seated due to frictional forces between its flank surfaces and the sides of the groove.  In a first em-bodiment, the diameter of the cavities is substantially larger than the diameter of the ball bearings, and the bear-ings are free to orbit within the cavities as the bearing cage rotates.  In the second embodiment, the cavities are only slightly larger in diameter than the ball bearings, but the radial width of the bearing cage is substantially less than the  width of the groove, and the bearing cage and the ball bearings together describe an epicycloidal path about the central axis of the bearing cage.  In both embodi-ments, the ball bearings seated within the cavities contact adjacent bearing races over a constantly changing portion of their surface.  This substantially extends the oper-ational life of the thrust bearings.
